JACOB LUNDGREN, OF Pill'l.iA.l).lfllyllllA, PENNSYLVANIA.

Application filed June l5,

the United- States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements .in Braiding-Machines, of which the following is a -directions to each other and wherein the threads delivered from one set oi bobhins are directed under and over thebobbins of the other set and the threads des livered therefrom to effect the braiding operation.

Heretoiore, in rnachines of this class, the threads deliver-ed from one set of bobbins were directedunder and over the bobbins oi the other setinalternate sue cession, thus producing a braided fabric wherein each thread extending in one direction. passed in alternate succession over and underA each thread extending in i the other direction.

It has long been desired to produce, in a machine of the class to which my invention relates, a means whereby each thread delivered from one set of bobhins may be passed over and under each succeeding two bobbins of-the other set in alternate succession and between each sricceedingtwo bobbins which were passed over and under by each threads preceding thread, there-hy producing a braided fabric wherein each thread eax*- tending in one direction passed, in alternate succession, overand under each succeeding two threads extending in the reverse direction-and between each succeeding two threads which were passed over and under by its two adjacent threads.v

Fo-accomplish this is the object of my present invention; and, with this Object in view, the invention consists-in the novel construction and combinations of parts which will be hereinafter fully described and claimed.

In the drawings Figure l is a central vertical section through myiiniproved braiding machine. Fig. 2 is 4a plan view, as seen from below the line 2--2 of Fig. -l. Figi-Sis a siinilar 'view having certain of the parts removed. Fig. 4 is a development showing several of the thread-guiding gear wheels, a portion o their actuating gear ring and, by duizend-dash line, the path traversed by the' threads delivered from one set of bobhins. Fig. 5 is a development of several .of the bobbin carriers, their traekway, their actuating gear wheels and a portion of the gear ring for actuating-the wheels. Fig. 6 is a sectional detail, as on the lineG-( of Fig. 2. Fig. 7 is a similar detail, as on the line 7--7 Specification of Letters Patent.

plate l and the standards 2 and 3. Rising [roin the bed plate 1l' is a centrallyarranged tubular post 4 which supports a iixed traine 5. Rotatably mounted on the post 4 above and below the fixed Iralne 5, respectively, are two frames or supports 8 and 9. The hub of the frame 9 is provided with a bevel gear wheel 10 in mesh with a siinilar wheel ll on the inner end of the main driving shaft l2 which is journaled in bearings 13 and 14 en the bed plate l and isprovided on its outer end with the usual driving pulley l5 and the adjacent loose pulley 16.

.loirneled in the fixed traine 5 is a vertical shalt 17 which is provided on its upper and lower ends with a small and large gear wheel. 18 and 19, respectively. The large gear wheel 19 is in mesh with a gear ring 20 fixed to the lower rotatable traine 9, and the small gear Wheel 18 is iu mesh with a gear ring 2l fixed to the upper rotatable frame S; to the end that when the main shaft 12 is actuated to rotate the lower frame 9, the upper lrarne 8 will, 'through the gear Wheels 19 and 18 and gear rings 2O and 2l, be rotated in the same di rection but at a slower rate of speed, due to the different diameters of said gear wheels and gear rings.

Formed on or secured to the upper frame 8 is a circular trackway 22, T-shaped in cross section, to which I is fitted a series of similarly shaped carriers 23 each of f one of a set of thread-supplying bobbins 24. Each carrier 23 projects outwardly beyond thetrackway 22 and is provided on its under side with gear teeth 25 in mesh with a series of gear wheels 26 arranged around the fixedA [rame 5 and journalcd on stud shafts projecting therefrom.

The lower frarne has axed thereto a gear ring 27 which coasts with the seri-es of geel-*wheels 26 in a manner to bodily rotate the series of carriers around 'the trackway 22 in a reverse direction to that of the lower frame 9, when power is applied to the driving shalt l2, the spaces between the carriers 23 and the gear wheels 26 being such that each carrier 23 .is in erigagenient with one ol the gear wheels at all times. The lower frame 9 carries a second set ofV thread-supn plying bobbins 28 and also a series of upwardly extend ing brackets 29 corresponding in number with the bobbins 28. The braclgets 29 are provided with een* ries of rotatable members 31 which, in the present in stance, are gear wheels adapted to coact with a fixed gear ring 32 supported by brackets 33 extending'from The main traine ofthe machine comprises the bed trally perforated studs 30 on which are journaled ase-x tyhich is provided with a projecting arm 23LL carrying guides 34 whicl1,-are adapted move toward and from' Vthe axes of rotation of said wheels during the oper-j ation of the machine. In the present instancethis is accomplished by extending through` each gear wheel'V 31, near its periphery, a,`centrally perforated stud' B5.' on which is mounted a freely rotatable gear wheel 36i carrying the thread guide 34. Thejgear wheel 36 is in.'

mesh with n gear wheel 37 xedon the inner endpi.` the stud shaft 30, whereby when'the gear wheel 31 isl rotated'upon"thestud'SO, the geen wheel'36 will be'rol tated upon the stud 35, the latter wheelmaking two complete revolutions for .each revolution 'fthe gear wheeler. L

. VThe threads 40 delivered-'from the'b'obbins 24, pass under and over suitable tension' wires 38 on the carriers 23 and then directlto the braiding point 39,'Iand each thread 41'delivered from the bobbins 2@ passes through guides 42 then through thestd 30, then through en opening 43 in the wheel 341|` then throughthe stud 35 and finally through'an eye` 44on-the free end of the `thread guide 34 projecting from the gear wheel 36. From the eye 44 each thread 41 parses tio .the braiding4 As'the lower franlelrotates, the gear'wheels-Sl are carriedbodily therehy"an`d,at the same time` the said `gesrwheels are individually rotated by their engage' ment with the fixed gear ring`32.

way 22 and the path traversedby the bobbins 24, the trackway being made in sections, as shown, and thus providing suitable openings 45 between adjacent sec- "tions into and out oi which the threads 41 are adapted to pass es they are being raised and' lowered. The arrange'-` 'l ment of theopenings 45 and the timing' of the movement ofthe upper frame 8 and perfoi'ce the trackway 221s such-as` to-cause the proporregister of the threads' *41`with the 'op en ings The 'gear wheels-36 are so arranged onthegear wheel 'l Bltliat when one gear 4wheel 36 is in the highest position its -`two adjacent gear wheelsS are in thelowest position andthe converse. Thus when one -half ofthe number:

raisedrthe other half thereof` v indicatedby the dot-and-dash line 46 in Fig. 4, and the timing o this peculiar up and down movement of the threads 41 with relation to the movement of the bobbins 24 is such as to cause each thread 41 to pass over'and under each succeeding two bobbius 24 and the threads 40 delivered therefrom, in alternate succession, and between each succeeding two bobbins 24 and the threads 40 delivered therefrom which were passed over and under by the preceding thread 41, thus effecting the braiding operation and the production of a braided starac" v 4 ,.Anfimportint feature of my invention is the arrangevment ofthe studs 3D and 35 each on'li'nes which pass direct tothe braidingv point 39. This arrangement maintains the thread delivery eyes 44 ata constant distahcehom the braiding-point 39 during the operation olthefmschine and obviates the otherwise necessity of ftakefnp devicesfor the threads41.

One end of this shalt' 5l is provided 'with a gear wheel 52 which coacte with a similar wheel 53 on o ne end of a short shaft 54.
